Basic joint size NM021 - NM125:
Press the pin (5075) out of the head of rotor (1999)
or connecting shaft (1050). If necessary use a ham-
mer and a thin cylindrical pin (DIN 6450 C).
Drain the oil into a receptacle.
Caution for pumps with ceramic rotors!
Where a pin (5075) may not come out easily, the
metallic head of rotor (1999) should be supported
on wooden blocks. Then the pin (5075) can be dri-
ven out with the help of a pin punch (DIN 6450 C).
This should be done with care, holding the ceramic
rotor with your hands.
Please dispose of this oil in the proper manner.
Using a screwdriver, carefully lever the SM-pin joint
seal (8235) out of the head of rotor (1999) or connec-
ting shaft (1050).
Taking care not to damage the SM-pin joint seal
(8235)!
Pull apart the rotor (1999)/ coupling rod (1998) /
connecting shaft (1050) assembly. Remove the O-
rings (8060).
Push the SM-pin joint seal (8235) towards the head
of coupling rod (1998). In the narrow coupling rod
section press the clamp ring (5425) out of the
groove of the seal. Then slip the SM-pin joint seal
(8235) and clamp ring (5425) off over the head of the
coupling rod (1998).
